Definitions
- the invention relates to a supporting bolt which serves to bridge a gap between two legs of a load-carrying means and which, in addition to a fixed end stop, has an captive securing element which can assume a securing position and a release position.
- Support bolts of the type described above are used in particular in connection with attachment points for chains, ropes or belts, such as are used e.g. encountered in large forming tools as an integral part of these tools.
- a support bolt of the type under consideration is known, which is provided with a fall ring lock.
- a fuse has the advantage that the securing element is captive, but the ease of use is also unsatisfactory for them, since the fall ring must be removed from its securing position by hand, at least when dismantling the support bolt before passing through the holes in the legs of the load suspension device, which in practice often leads to finger injuries to the operators.
- the known fuse is based on the principle of gravity, it is also susceptible to contamination.
- the invention has for its object to provide a support bolt that is easy to handle and offers a high level of security.
- This object is achieved according to the invention in that the support bolt is provided with a transverse bore and a longitudinal bore intersecting the transverse bore and in that a locking pin and a spring which presses the locking pin into the locking position are arranged in the transverse bore, while an actuating pin for the locking pin is guided in the longitudinal bore, the locking pin having a recess with an inclined surface, via which a section of the actuating pin guided in the recess provides a the spring force, the movement of the locking bolt from its securing position, can be introduced into the locking bolt.
- the support bolt according to the invention has the advantage that it can be quickly and easily assembled and disassembled. There is no need to fear that the fuse will be adversely affected because all the parts that are important for the function are arranged inside the support bolt.
- FIG. 1 is a front view of a so-called support beam, the space between which is delimited by legs is bridged by a support bolt,
- FIG. 5 shows a detail V in FIG. 2 on an enlarged scale
- FIG. 6 shows a first perspective illustration of the parts of the securing of the supporting bolt
- FIG. 7 is a second perspective view of the parts securing the support bolt, 8 on a larger scale than in FIG. 3, a section through the support bolt according to FIGS. 1 to 7 in the securing position,
- Fig. 9 on an enlarged scale compared to Fig. 3 shows a section through the support bolt according to Figures 1 to 7 in the unlocked position
- Fig. 10 on an enlarged scale compared to Fig. 3 shows a section through the support bolt according to Figures 1 to 7 during the assembly or disassembly of the parts forming the fuse.
- 1 and 2 are the legs of a load suspension means formed by a so-called support beam 3.
- the legs 1 and 2 delimited an intermediate space 5 bridged by a supporting bolt 4, which can be plugged through an end link (not shown) of a chain sling or through the thimble of a hoisting rope.
- a position securing device In order to ensure that the carrying bolt 4 does not unintentionally come loose when lifting a load to which the carrying beam 3 is screwed or welded, it is provided with a position securing device. It consists on the one hand of an end stop 6 formed by an annular flange and on the other hand of a locking pin 7 which is pressed into a locking position by a spring 8, from which it can be removed with the aid of an actuating pin 9.
- the locking bolt 7 and the spring 8 are accommodated in a transverse bore 10 which intersects a longitudinal bore 11 in which the actuating bolt 9 is guided.
- the actuating pin 9 has at its free end an inclined surface 12, which is followed by a locking cam 13 which engages behind the locking pin 7 in the assembled state of the actuating pin 9, in order in this way the cohesion of Secure actuating pin 9 and locking pin 7.
- a stop surface 15 running perpendicular to the longitudinal axis 14 of the actuating pin 9 limits the stroke of the actuating pin 9.
- the end of the actuating bolt 9 which has the latching cam 13 engages in a recess 16 in the locking bolt 7, which has an inclined surface 17 which is intended for interaction with the inclined surface 12 of the actuating bolt 9.
- the inclined surface 17 of the locking bolt 7 has an angle ⁇ of approximately 50 ° with the longitudinal axis 18 of the locking bolt 7, while the angle ⁇ between the
- Inclined surface 12 of the actuating bolt 9 and its longitudinal axis 14 is approximately 40 °.
- the locking bolt 7 is equipped with a further inclined surface 19, which has an angle ⁇ of approximately 60 ° with respect to the longitudinal axis 18 of the locking bolt 7.
- the locking pin 7 is provided with an insertion groove 23 which the locking cam 13 can pass if the locking pin 7, for example with the aid of a pencil or dome, in the direction of the arrow 24 is pressed against the action of the spring 8 in the position shown in Figure 10.
